Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

Monarchidae
The monarchs (family Monarchidae) comprise a family of over 100 passerine birds which includes shrikebills, paradise flycatchers, and magpie-larks. Monarchids are small insectivorous songbirds with long tails. They inhabit forest or woodland across sub-Saharan Africa, south-east Asia, Australasia and a number of Pacific islands. Only a few species migrate. Many species decorate their cup-shaped nests with lichen. Taxonomy and systematics Some of the one hundred or more species making up the family were previously assigned to other groups, largely on the basis of general morphology or behaviour. The magpie-lark, for example, was assigned to the same family as the white-winged chough, since both build unusual nests from mud rather than vegetable matter. That family, Grallinidae, is now considered a synonym of Monarchidae. It was formerly considered to have four species. The magpie-lark and the torrent-lark were moved into Monarchidae, into the genus ''Grallina'', on the basis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dyaul Island
Dyaul Island (also Djaul) is an island in New Ireland Province, Papua New Guinea Papua New Guinea (abbreviated PNG; , ; tpi, Papua Niugini; ho, Papua Niu Gini), officially the Independent State of Papua New Guinea ( tpi, Independen Stet bilong Papua Niugini; ho, Independen Stet bilong Papua Niu Gini), is a country i .... Its area is 100 km2. The inhabitants live mainly in seven villages, and frequently visit Kavieng, the capital of the province, for supplies or to sell produce and fish. There are two languages, not counting Tok Pisin, spoken on Dyaul; Tigak and Tiang. Tigak is widely spoken on the western end of the island in two villages. Tiang is spoken across the remainder of the island. References Islands of Papua New Guinea New Ireland Province {{PapuaNewGuinea-island-stub ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Myiagra
''Myiagra'' is a genus of passerine birds in the family Monarchidae, the monarch flycatchers, native to Australasia, sometimes referred to as the broad-billed flycatchers or simply broadbills. Taxonomy The genus ''Myiagra'' was introduced in 1827 by the naturalists Nicholas Vigors and Thomas Horsfield. The name combines the Ancient Greek ''muia'' meaning "a fly" and ''agreō'' meaning "to seize". Myiagros was also the name of a Greek god. The type species was designated by George Robert Gray in 1840 as the leaden flycatcher. Species The genus contains 22 species include one that is now extinct: * Oceanic flycatcher (''Myiagra oceanica'') * Palau flycatcher (''Myiagra erythrops'') * † Guam flycatcher (''Myiagra freycineti'') (extinct) * Pohnpei flycatcher (''Myiagra pluto'') * Moluccan flycatcher (''Myiagra galeata'') * Biak black flycatcher (''Myiagra atra'') * Leaden flycatcher (''Myiagra rubecula'') * Steel-blue flycatcher (''Myiagra ferrocyanea'') * Makira flycatcher ('' ...
